Abstract: A non-biodegradable endodontic sealant composition comprises the reaction product of a first paste and a second paste. Either paste or both pastes include one or more of: unmodified HEMA and bioglass. The first paste includes a first polymerizing agent and the second paste includes a second polymerizing agent. A method for making the composition comprises preparing the first paste and second paste and combining the pastes under conditions to achieve a polymerization reaction initiated by a reaction between the polymerizing agents. The combining step is performed under conditions for achieving a setting time that is in a range of about 1 minute to about 1 hour. A method for treating humans having a voided region into which no re-growth will occur comprises administering the composition to the affected area, preferably to an area where tissue, tooth, or bone are not intended to re-grow.
